A group of scientists studying a broad range of Arctic systems — from sea ice to permafrost to the Greenland ice sheet — gathered in D.C. to lay out just how extreme a year 2016 has been so far for the northern cap of the planet. “I see the situation as a train going downhill,” said Lamont's Marco Tedesco. “And the feedback mechanisms in the Arctic [are] the slope of your hill. And it gets harder and harder to stop it.”
The risk of rapid coastal subsidence to infrastructure and economies is global and is most acute in large river deltas, which are home to about 500 million people. An international community of researchers is calling attention to the need for better measurements and modeling and linking the science with its socioeconomic implications, Lamont's Michael Steckler and colleagues write.
A megathrust fault could be lurking underneath Myanmar, Bangladesh, and India, exposing millions of people to the risk of a major earthquake, according to research led by Lamont's Michael Steckler.
Lamont's Colin Stark visited the Glacier Bay landslide and said closer inspection revealed two big discoveries: the slide was still active days later, and the original landslide was so powerful it pushed rock and dirt up the sides of the valley almost 300 feet.
It's the second summer for the Biking While Breathing project which looks at the impact of air pollution on exercise in New York City. This year, researchers are considering going cheap. Cites Steve Chillrud's work.

Seismic recordings registered a massive landslide in Alaska's Glacier Bay National Park, and scientists are studying how the region's geology and environmental change are elevating the risk of mountain landslides. Cites work by Colin Stark and Göran Ekström.
More than 100 million tons of rock slid down a mountainside in Southeast Alaska on Tuesday morning, sending debris miles across a glacier below and a cloud of dust into the air. Lamont's Colin Stark and colleagues analyzed the landslide through its seismic waves.
Slowdowns of the Atlantic meridional overturning circulation have long been suspected as a cause of the climate swings during the last ice age, but never definitively shown, until now. The new study “is the best demonstration that this indeed happened,” says Lamont's Jerry McManus.
A new study led by Lamont's Ryan Abernathey shows how sea ice migration around Antarctica be more important for global ocean overturning circulation than previously thought. (In Spanish)
The burning sensation in the southwestern United States was diagnosed by climate scientists more than a year ago, the Washington Post writes. The Post cites research by Lamont-Doherty scientist Park William into connections between the California drought and climate change.
California's overworked firefighters are being forced to take on another task — clearing dead and dying trees. John Upton talks with Lamont's Park Williams about the role of drought and rising temperatures.
High-resolution ocean models that can capture eddies are extremely important for understanding the fate of freshwater in the sea around Greenland, says Lamont's Marco Tedesco.
The fact that water vapor is the dominant absorber in the Earth’s greenhouse effect can lead to a flawed narrative about the role of anthropogenic carbon dioxide (CO2) as driver of climate warming. Lamont's Adam Sobel helps explain.
Last summer the northern parts of the Greenland Ice Sheet experienced record melting as summer temperatures rose as high as 66°F. Now, a group of scientists led by Lamont's Marco Tedesco has linked the melt pattern with a high-pressure vortex, known as a block, that loitered north of the island during June and July 2015, wreaking weather havoc. Some researchers say such atmospheric blocks are expected to result from melting sea ice.
Climate change has pushed up average temperatures by nearly 2°F worldwide. Most of California was warmer than that from March through May, with some patches of the state more than 4°F warmer than average. “This does not look like a typical El Niño year out West,” said Lamont's Ben Cook.
The globalization of the world's economy this century has made it far more vulnerable to the impacts of extreme weather, including heat stress on workers, according to a new study from Lamont's Anders Levermann.
2015 was a record year for high temperatures and melting glaciers in western Greenland, an effect that is amplifying itself and could lead to accelerated warming in the Arctic, new research from Lamont's Marco Tedesco explains.
Researchers working in Iceland, including Lamont's Martin Stute, say they have discovered a new way to trap the greenhouse gas carbon dioxide deep underground by changing it into rock.
